PATTERN-WHEEL FOR WARP-KNITTING MACHINES.

SPECIFICATION forming part of Letters Iatent No. 39813.93, dated February 26, 1889.

March 22, 183,8.

To all wtfmrz may Concern:

Be it known that l, JAMEs KEETON, of Brooklyn, in the county ot Kings and State f of New York, have invented anew and useful In'lproven'ient in Pattern-fheels for \'\`Yarp- Knitting` Machines, of whieh the followingr is a full, elevar, and exaet description.

This invention relates to pattern-wheels ol warp-maehines used in making' `gloves., mitts, and other like articles ortabries. Ordinarily the patternovheel in sueh machines, whieh op erates, throl'lg'h the int erven tion ot a lever, the guide-intr that earries the guides in whieh the warp-threads to be worked pass, has its eirk eumtferential or aeting' surli'aee made up of a series ot' lixed or 1ion-adjustable projet-.tions or rlepressions that set in or out, aeeording' to g the pattern. to be In'odueed or labrie to be I worked. When a Change in the pattern or tabl-i0 to be produeed isreqn'ired to be made, then it is usual either to top ol'f in the lathe the rioting-surface oli the wheelV and afterward to tile down the blocks which are required to have a depressed position upon said aetingsurt'aee, o1' else to separatelyattaeli,byserews or otherwise. additional or re-enl'orein pieces upon the bloeks, whieh are required to oeouplv a projet-ting' position upon the aeting'surfaee in order that the wheel when rotated will rive the neeessarv hitting'movementslotheg'uidebar which (.1 ies the guides, and so eause the warp-threads lliassing through the `guides to be eorresponding'lyv shifted to produce a `given pattern or tabrie. Sueh alterations ot the pattern-wheel take eonsiderable time and labor and are neeessarilv expensive. To ohviate this, the bloc-ks oi' the pattern-wlmel have been made adjustable, and so that they ma \v he in depemlently set in orout relat ive| v to the eenter ot'the wheel; and lnvinvention eonsists in a novel construction, arrangement, and eombinatiou oi' parts t'or sueh purpose, substantially as hereinafter described, and pointed out in the elaims, and whereby iaeility is aflorded for adjusting' the bloelts from their e.\' terior or aetine,` i'aees, eapable ot' being' set independentl'vin or out relativelyto the eenter oi' the wheel, so as to change the pattern as required; and the invention 'further Consists in a special Construction of such wheel and of the means used tor holding' and adjusting the in which similar letters of reference indieate l corresponding' parts in all the iig'ures.

Ifig'urey represents a partly-broken and partltv-seetional plan view ot a patternm'heel for warpanaehines embodying' my invention,

also showing' the lever a nd port ion of theg'u idebar operated by the pattern-wheel. Fig'. Q is a transverse seetion upon the line .rrr in Fig'. l ot the same; and Fit'. i3 is aviewin perspective, upon a larger scale, ot` one ot" the bloc-.lis and ot.' a serew-bolt used for holding and adjustine' it', detached.

The wheel, which is earriel'l, as usual` by an upright rotatable spindle, A, is Composed in part olf a hub, l, with att'aehed web Z1 and rim e. Opposite side or `faee plates, C C, arranged to projeet beyond the rim e, are seeured in position by means ot' screws (l, passing' through them and through the web i), whereby said face-plates are removal'lle when .required to take out or replace any ot the hloeks D, and tor the Convenient-e ot' inserting' said blocks and their means ot adjustment when first putitin the wheel together.

The segmental blocks l), whieh t`orn1 the aettine'surtaee ot` the wheel to operate the. usual lever, l,that gives motion to the guide-MWF,

that Carries the `guides through whieh the warpthreads pass, are fitted to slide radiali;`

' relatively to the center oi the wheel between the face-plates C C and the web li of thewheel, wherelnsaid bloelcs ma v l e in d ependentlv set in or out to vary the pattern` as required. To

" thus adjust the blocks l) and to hold them to theirplaees when adjusted, they are eaeh fitted with a swiveled serew-bolt, G, arranged to pass through them and through slots e in the rim e of. the wheel. Said serew-bolts are eaeh eonstrueted with double heads or shoulders s s at a suitable distanee apart to receive the rim t:

ol' the wheel in between them, and have a serew-tlu'ead on their outer end portions whieh pass through the bloeks, wit-h a niek in their iront ends for tu rni n the bolts, by screwdriver or otherwise, to adjust the several or any ot the bloeks in or out, as required, ae-

IOO

cording to the irregularity of the acting-surface of the Wheel needed to produce the fabric or vary the pattern, as required.

The object of the slots e in the rim is to provide for fitting the double-head ed sWiVeled screw-bolts G, with their attached blocks, to their place and for removing the same, if neoessary, the face-plates C being Alirst removed.

It is designed in setting the Wheel to start at a given diameter, which may be the usual one of such Wheels, and then to form the necessary irregularities on its acting-surface by extending or adjusting' and setting out the blocks, as required.

Having thus described my invention, what I claim as new, vand desire to secure by lietters Patent, is-

l. The combination, with the hub, theI web, and the rim, of a series oli' radial]y-adjustable and having central longitudinal threaded apertures, and screw-bolts swiveled at their inn er en ds in the said rim and extending through outer ends and two shoulders, s s, at their inner ends at opposite sides of the rim, the portions of the bolts between the shoulders passing radially through the slots, the radially-adjustable segmental blocks D at opposite sides of the web beyond the rim and having longitudinal threaded apertures, through which the blocks forming the working-face of the Wheel threaded portions of the bolts pass to the Working-faces of the blocks, the removable faceplates C at opposite sides of the web closing the slots in the rimY and extending alongside of the blocks, and the screws d, securing said plates in position, substantially as set forth.
